The neotropical plant, Lantana camara L., introduced as an ornamental plant to several countries, has become invasive weed. It was first reported from Nepal in 1848. About 50 countries have natural enemies for suppression of the India, Nepal’s neighboring country, initiated biological control this weed 1916 and occurrence Lantanophaga pusillidactylus Walker. In a recent survey, Feed future Inte...

Mile-a-minute weed, Persicaria perfoliata (L.) H. Gross, is an invasive annual vine of Asian origin that has developed extensive monocultures, especially in disturbed open areas in the Mid-Atlantic region of the United States. A host-specific Asian weevil, Rhinoncomimus latipes Korotyaev, was approved for release in North America in 2004, and weevils have been reared at the New Jersey Departmen...

This paper analyses the potential and limitations of airborne remote sensing systems for detecting crop growth variability and weed infestation within paddocks at specified capture times. The detection of areas of crop growth variability can help farmers become aware of regions within their paddock where they may be experiencing above and below average yields due to changes in soil or managemen...

Weeds As Examples Weeds provide good examples to clarify what is meant by an invasive species because most people have a concept of what constitutes a " weed. " Invasion can be thought of as a process that in our example, a plant must go through to become a successful, yet harmful invader. Several barriers must be overcome for a plant to be considered an invasive weed. Invasive weeds are invasi...

At this time CDF anticipates the possible use of the following herbicides for invasive weed control and reforestation purposes: Clopyralid, Glyphosate, Imazapyr, Sulfometuron methyl, and Triclopyr. New products, formulations and application techniques may provide better control and improved environmental toxicology profiles. The listed products may prove to be ineffective on a specific species....

Ever-increasing demand for water to irrigate crops, support aquaculture, provide domestic water needs and to protect natural aquatic and riparian habitats has necessitated research to reduce impacts from a parallel increase in invasive aquatic weeds. This paper reviews the past 4-5 years of research by USDA-ARS covering such areas as weed biology, ecology, physiology and management strategies, ...
